Reputation changes are constantly out of sync with SO account:
This is how it first look on my SO account:
This is the reputation changes I see in the new bar (which I opened later) :
shouldn't the reputation changes in the new bar show only "new" notifications? (that wasn't read somewhere else, in this case - it shouldn't show anything..).
This happened to me multiple times today (even if I opened meta an hour after I already saw the change in SO).
